ble of effecting the different operations necf essary to convert thecream into finished butter. The advantages resulting from thus combiningin a single machine the capacity for effecting the series of operationsheretofore carried on successively in two or more separate mechanismsconsist not only in the savingof rst cost of apparatus and of valuableroom, Y

but also in the saving of unnecessary handling, and particularly in theimproved quality of product resulting from the entire avoidance ofvexposure of the easily-affected material operated on. Y

Heretofore the cream after being separated from the whole milk has beenirst' subjected r to a tempering operation, whereby itis ripened forchurning, this being eect'ed in a special apparatus. The succeedingoperations of churning and working have 'been carried on either in twoseparate machines or in a combined churn and worker. My iniprovedmachine is adapted not only to effect all of these operations withoutrequiring any handling or transfer of the cream except from the creamseparator directly into 'the machine, but it is also adapted to carry oneither one of the operations independently of the.

others, if desired.

The features of my invention are fully described in connection with theaccompanying drawings and are particularly pointed out in the claims.

Figure 1 is a longitudinal sectional view of a machine embodying myinvention, one of the paddles and one of the working devices only beingshown. Fig. 2 is a partial crosssectional view indicating differentpositions of the working devices.

A represents a'vessel, preferably of cylindrical form, having heads Aland A2, provided with hollow gudgeons which are mounted in bearings C Cand which receive a central shaft or bar B, extending longitudinallythrough the vessel, said shaft, as shown, being extended entirelythrough the gudgeon a of the head A and being adapted to be securedeither tothe xed bearing C or to the rotary vessel A, as hereinafterdescribed.

The Yvessel A is provided with a series of paddles E, which are madehollow, as shown, and are carried between the heads of the vessel andconnected together, so as to form a continuous passage for rliquid bypipes E2, which pass alternately throughthe heads A2 A', while theunconnected end paddles of the series are connected, respectively, to aninlet-chamber a', formed in the gudgeon a, and to an outlet-chamber a2in the same by means of an inlet-pipe E' and an outlet-pipe E3,respectively, as indicated, The liquid which is to be circulated throughthe connected hollow paddles may bc supplied to the gudgeon-chamber a,as shown, by means of an annularlychambered feed-sleeve D, ixedlymounted on the projecting shaft B and arranged to form a liquid-tightconnection with the rotating gudgeons,while the circulated liquidreturned to the chamber CL2 may be delivered therefrom in any preferredmanner. p'

'As thus describedit will be understood that my improved machine isadapted to serve as a creamvat and ripener and also as a churn, thecream being tempered in order to better control the ripening bycirculating a liquid of any desired temperature through the connectedpaddles while the latter are being slowly rotated with the loaded Vesseland being subsequently'churned, as usual,without transfer to anothervessel,.thus avoiding the exposure and expense incident to suchadditional handling. Also inasmuch as it is similarly advantageous toeffect the required working of the butter without incurring suchexposure and expense I provide, in connection with the.

tempering and churning mechanism already described, a working deviceWithin the vessel A, so arranged as to be either put into working actionby the rotation of the vessel or to be locked against such action, asdesired. This butter working mechanism comprises, as shown, a workingdevice, preferably in the form of a longitudinally arranged bar orrollers G, carried bylinks l'l, which have their inner ends pivoted atff' to arms F, fixed to the central shaft B, the length of these armsand of the connecting-links being such as to cause the working device Gto be swungin an arc g by the passage of each paddle E of theslowly-rotated vessel, the central shaft B and connected arms F beingrigidly held during this action by fixing the former at l) to thebearings C2. The movement of each link l-l upon its pivotal connection fis, as shown, limited in each direction by stopsf and f2, so as to allowthe roller G to swing a limited distance both above and below the radialline f3 and so that said roller approaches nearest to the inner wall A3of the vessel at an intermediate point of the rollers movement. Theroller G in its upward swing moves inward on the arcl g suiiciently toallow the paddle E by which it has been moved to pass it, as indicatedat G', after which it falls to its lowermost position in the arc g, onlyto be again raised by the next succeeding paddle E.

The working of the butter, as will be readily understood, is effected bythe action of the roller G upon the mass of butter carried upward by thepaddles E,which may be not only pressed against the paddles by thefall'of said roller, but is also pressed against the wall of thevesselby the movement of the same in the arc g.

During the tempering and churning operations the working action of thebar or roller G in connection with the paddles E is not required, and Itherefore provide for conveniently dispensing with this action whendesired. This I accomplish, as shown, by locking the roller mechanism tothe rotary vessel, so that it,together with the shaft B,will simplyrotate with the vessel, which Iaccomplish by merely removing the pin b,which fixes the central shaft B to the bearing, turning the shaft untilthe arms F and rollers G assume the dotted position, indicated in Fig.2, with the latter held against the paddles E,and then pinning the shaftB to the vessel, as at b', so that shaft and all will rotate with thelatter.

It will be understood that the arm F, from vwhich the roller G is shownsuspended,would most naturally be swung upward, so as to lock the link Hin contact with the upper paddle E instead of with the lower one, asindicated by the dotted lines, which latter would in such case representa roller and link attached to the second (lower) arm F.

It will be seen that the paddles E in connection with the vessel A arethus adapted series of operations are thus effected not only in a singlemachine, but without handling or exposure of the material at any stageof the process.

It is obvious that the mechanism specilically shown and described may beconsiderably modied without departing from the spirit of my invention.
